The Banda Islands, Tanimbar Islands, Kai Islands and other smaller islands in the Banda Sea have been designated as the Banda Sea Islands moist deciduous forestsecoregion, the eastern end of the Wallacea biogeographical region containing a mixture of plant and animal species from both Asia and Australasia. These islands are covered in mostly intact rain forest and home to a number of endemic plants and animals including twenty-one birds, a very high number for this small ecoregion. There are only twenty-two mammals on these islands including three endemics, the rare Dusky Pademelon(Thylogale brunii) and Tomb Bat (Taphozous achates), and an endangered mouse-eared bat, the Kei Myotis(Myotis stalkeri). The birdlife is threatened by egg collectors and even more by cats and rodents that have been introduced to the islands. Yamdena in the Tanimbar Islands is an example of a large and fairly unspoilt habitat and is a protected area.[7] The base for visiting these islands is by plane or ship from Ambon Island to the north, the largest of the Maluku Islands. The Banda and Kei Islands, although remote are visited by tourists for snorkelling and for their unspoilt beaches.
